Booting
After that the system has been prepared for an iSCSI boot and the operating system is present on the iSCSI target, the last
step is to perform the actual boot. The system will boot to Windows or Linux over the network and operate as if it were a
local disk drive.
1. Reboot the server.
2. Select CTRL+S.
3. From the Main menu, select General Parameters and configure the Boot to iSCSI target option to Enabled.
4. To boot through an offload path, set the HBA Boot Mode to Enabled. To boot through a non-offload path, set the HBA
Boot Mode to Disabled.
If CHAP authentication is needed, enable CHAP authentication after determining that booting is successful (see
Authentication).

Other iSCSI Boot Considerations

There are several other factors that should be considered when configuring a system for iSCSI boot.

Locally Administered Address

A user-defined MAC address assigned through the Locally Administered Address property of the Advanced section of the BACS
Configurations tab is not supported on iSCSI boot-enabled devices.

Virtual LANs

Virtual LAN (VLAN) tagging is not supported for iSCSI boot with the Microsoft iSCSI Software Initiator.

Troubleshooting iSCSI Boot

The following troubleshooting tips are useful for iSCSI boot.
Problem: When switching iSCSI boot from the Microsoft standard path to Broadcom iSCSI offload, the booting fails to
complete.
Solution: Install or upgrade the Broadcom Virtual Bus Device (VBD) driver to 5.0.x, along with the OIS driver, prior to
switching the iSCSI boot path.
Problem: The iSCSI configuration utility will not run.
Solution: Ensure that the iSCSI Boot firmware is installed in the NVRAM.
